  • FIG. 8 is a modification of the example shown in FIG. 1, in which the application brush 10 of FIG. 1 has a brush width over the entire length of the tube-shaped film 7, and in this case, the application brush The lash 10 'and the holding cylinder need not perform the relative linear motion as long as they perform the relative rotational motion.
  • the relative movement between the auxiliary liquid supply means and the holding cylinder is limited to the linear movement. It is not necessary to provide the rotation motion.
  • An ammonia solution of sodium metal or a tetrahydrofuran solution of a sodium / naphthalene complex is supplied into the fluorine resin tube held on the inner peripheral surface of the holding cylinder by the supply means shown in FIGS. After contacting for a certain period of time, alcohol and then water are supplied by the same supply means, and then dried to obtain a fluororesin tube having good wettability.
  • Substances that can be surface-modified by ultraviolet laser irradiation include fluororesin, polyester, polyetheretherketone, polyimide, polyetherketone, polyphenylenesulfide, aromatic polyamide, polyarylate, and polyetherimide. , Polyamide, polysulfone, polyethersulfone, polystyrene, polymethyl methacrylate, and polyurethane. Further, a mixture thereof may be used.
  • polyethylene, polypropylene, polyamide, etc. can be surface-modified with ultraviolet laser light if UV-absorbing substances are contained in the resin in advance or applied to the surface of the resin in the same way as fluorine resin. It is.

Abstract

L'invention concerne un film tubulaire de résine fluorée, présentant une surface intérieure exempte de plis et traitée de façon homogène, ainsi qu'un appareil et un procédé permettant de traiter la surface intérieure dudit film tubulaire. Le dispositif présenté comprend un moyen de fixation (1) servant à retenir un film tubulaire (7) à traiter sur la surface d'un cylindre (2) tout en maintenant la forme cylindrique de ce film, et un moyen de traitement (8) et/ou (11) qui est inséré à l'intérieur du cylindre pour traiter la surface intérieure du film tubulaire maintenue sur la surface intérieure du cylindre. Le moyen de fixation et le moyen de traitement sont conçus de façon à effectuer un mouvement de rotation à vitesse constante et un déplacement linéaire également à vitesse constante, l'un par rapport à l'autre.
